INTRODUCTION.
Soon after I had the honour of being appointed Her Majesty's
Astronomer at the Cape, in 1879, I directed the attention of the
Lords Commissioners of the Admiralty to the fact that no
adequate equipment for refined extra meridian observations
existed at the Observatory. Before making further official
proposals to remedy this defect I had the good fortune to
procure, by private purchase, the Heliometer which I had used
at Dun Echt, and in connexion with the expedition of Lord
Lindsay (now the Earl of Crawford and Balcarres) to the Island
of Mauritius in 1874, when I observed with it the opposition of
the minor planet Juno,* and which I afterwards employed by
Lord Lindsay's kind permission, in the Royal Astronomical
Society's expedition to the Island of Ascension to observe the
opposition of Mars in 1877.t
The instrument as employed at Mauritius and Ascension is
fully described in the Dun Echt publications, Vol. II. For use
at the Cape I could not obtain the original equatoreal mounting,
and therefore ordered a new stand for the Heliometer tube and
cradle from Sir H. Grubb of Dublin, taking advantage of
the opportunity thus offered to have some alterations made on
the instrument which previous experience had proved to be
desirable. These alterations were chiefly in connexion with the
slow motion of the tube in position-angle. In the original
instrument the quick motion in position- angle was accomplished
by turning a rod, which carried a pinion which acted on a wheel
of which the Heliometer tube formed the axis. Slow motion
was given by rotating this rod very slowly by means of a
toothed wheel acted on by a tangent screw, but the effect was
to create a certain amount of torsion of the rod before any
rotation of the tube took place, so that there was wanting that
immediate and precise response to the observer's action which is
essential for easy and accurate measurement. I therefore planned
the following arrangement. •
At the end of the cradle next to the observer, there is fitted
on the tube (or rather on one of the collars attached to the tube)

a ratchet wheel with square cut teeth. This wheel is so fitted
as to turn smoothly on the collar, but, when the observer so
desires, it can be clamped firmly to the tube by a handle coming
down to the eye-end. A steei screw with a square-cut thread
(such as Grubb uses for the driving screws of his Equatoreals)
acts on the teeth of this wheel, whilst the pivots of this screw
rest in bushes in a frame attached to the cradle. The screw is
turned by bevel wheels acted on by a handle coming down to
the eye-end. When the observer turns the handle the wheel
slowly rotates; and, if the tube is clamped to the wheel, a
smooth easy rotation is communicated to the tube. This slow
motion as well as the Equatoreal mounting, and the driving
clock were admirably constructed by Sir. H. Grubb and the
instrument was in every respect efficient, stable, and convenient.
During a visit to some of the principal European observatories,
before my departure for the Cape, I met Mr. W. L. Elkin, a
student under Professor Winnecke, who was then engaged in
preparing his " Inaugural Dissertation " for the Degree of
Doctor of Philosophy at the University of Strasburg. The
subject he had selected was the orbit and parallax of a Centauri
and he applied to me for any observations of « Centauri as a
double star, or any unpublished meridian observations of a )3
Centauri which I might find on the records of the Cape
Observatory.* In the course of conversation I informed Mr.
Elkin of my purchase of the Heliometer, and of the purposes to
which I intended to apply it. He expressed much interest in
my programme and his keen desire to take part in such work,
It was finally arranged that, on the completion of his curriculum
and on the arrival of the Heliometer, Dr. Elkin should come to
the Cape and share my labours.
The Heliometer reached the Cape in the end of December
1880 (the Lords Commissioners of the Admiralty having
defrayed the cost of transport), and I proceeded at once to erect
it in an old observatory which had been built by Sir Thomas
Maclear in 1847, to cover a small telescope by Dollond. This
observatory is described in Mem. R.A.S., vol. xx., pp. 31-34.
I had duly completed the necessary alterations of the building,
and the adjustments of the instrument when Dr. Elkin arrived
at the Cape, on 1881, January 31. The following month was
spent in preliminary experiments, in the selection of stars of
comparison, and in the preparation of a programme.
* These observations I supplied soon after my arrival at the Cape, and they are
incorporated in his Dissertation " Ueber die Parallaxe von a Centauri." Karlsruhe,
1880.
This settled, I was en the point of leaving for Durban and
Aden to carry out the longitude operations connecting these
places with the Cape, when I was suddenly recalled to England
on urgent private affairs. I made new arrangements for the
longitude work, so that when I returned to the Cape on 1881,
June 30, I was enabled to take up the programme of the Helio-
meter observations at an earlier date than I originally intended.
Dr. Elkin occupied my house in my absence, and remained as my
guest, and as a member of my family circle until the completion
of our programme. He sailed from the Cape on 1883, May 16.
His work from first to last was a labour of love.
The results of the observations contained in this volume have
been published in the Memoirs of the Royal Astronomical Society,
vol. xlviii. ; but in connexion with such work it is usual and
desirable to publish sufficient details of the original observations
to enable other Astronomers to verify the subsequent com-
putations.
In the selection of comparison stars the conditions aimed at
were : —
1. Symmetrical situation with respect to the star whose
parallax is to be determined, that is to say, nearly at
equal distances from it, and different in position-angle
nearly 180°. As far as possible these position-angles
should nearly coincide with the position-angle of the
major axis of the parallactic ellipse, but when several
pairs of comparison stars are employed this condition
cannot of course be fulfilled.
2. Both comparison stars should be nearly of equal mag-
nitude.
3. They should be stars having little or no proper motion.
The following are the positions of the comparison stars as
determined with the Cape Transit Circle, and the adopted
position-angle and distance from the principal star ; the other
existing observations reduced to the same equinox will be found
in the Mem. R.A.S., loc. cit.

A complete observation consists of the following processes : —
1. The Position Circle is set to the required position-angle
and the segments separated in distance the requisite
amount.
2. The axis of the tube is directed, by means of the Hour and
Declination Circles, to the middle point between the stars
to be observed, when the images of the two stars are seen
together in the field of view.
3. The observer, by slow motion in position-angle and distance,
now brings the images to near contact, especially adjust-
ing the distance as nearly as possible. This latter adjust-
ment cannot be accurately made by superposing the
images ; the best practical method is to first place the
images of the two stars so that, while the discs are nearly
in contact, the line joining their centres shall be at right
angles to the direction of measurement. The estimation
of this condition is facilitated in two ways : 1st, the
images formed by semi-lenses are not circles but ellipses,
and when the definition is good and the stars are suffi-
ciently bright, the most accurate plan is to make the
major axes of the two ellipses coincident. The accuracy
of this estimation is greatly enhanced by immediate and
frequent interchange of the two images by use of the
slow motion in position-angle. The symmetrical emer-
gence of the elliptical discs from behind each other in
alternate opposite directions forms the most refined
method of " pointing " known to astronomers. When
the images are very faint or ill-defined, the power of
estimating distances in this way is not available, because
the major axis of the ellipse cannot be precisely distin-
guished. To provide for this, four flat intersecting wires
were inserted, in the common focus of the object glass and
eye-piece, forming a square, in the centre of the field, two
gides of the square are parallel to the direction of motion
in distance, and two at right angles to this direction.
The observer takes the latter pair of wires as his guides,
and by motion of the " distance-handle " adjusts the
position angle of the artificial close double star parallel
to the direction of these wires. This observation is
analogous to that, in which an observer with a parallel-
wire micrometer adjusts the wires parallel to the line
joining the centres of the double star whose position
angle he is measuring, but with this difference, that the
latter moves the position-angle of his micrometer till the
Vlll
wires are parallel to the stars under observation, whilst
the Heliometer observer changes the apparent position-
angle of the artificial double star by motions of his
" distance-handle " until the line joining the components
is parallel to his guiding wires. Immediately " crossing
through " (i.e., exchanging the relative positions of the two
stars), he verifies his former observation, and, if he finds
it confirmed, proceeds to read the scales. The eye is
very sensitive to the symmetrical crossing of the stars and
readily detects any apparent change of parallelism in the
guiding wires as such error in the first pointing is doubled
after " crossing through."
The accuracy in pointing by either of these methods is greatly
enhanced when the two images are precisely similar, hence the
great attention paid to the construction of the screens employed
to equalize the images. These screens were constructed of one,
two, and three thicknesses of wire gauze of different mesh, and
by careful selection and trial little difficulty was found in pro-
curing satisfactory equalization of the images ; the light of
Sirius, for example, being reduced to such perfect equality with
that of the comparison stars « and @ (7th magnitude) that it was
impossible to distinguish the image of Sirius from that of the
comparison stars, either by the difference of brilliancy or by the
appearance of the disc, when both were viewed near the centre
of the square. If the images of the comparison stars differed in
magnitude the screen was, as a rule, adjusted so as to reduce
the brilliancy of the principal star to the mean brightness of the
comparison stars.
When the observer has completed a " pointing " in the manner
described, he reads the scales as already mentioned.
The " scales " are of silver, attached to the two slides which
carry the halves of the object-glass and are divided into 150
divisions figured at each tenth division. The microscope views
both scales at once and (approximately) when the readings of
the scale are identical the optical centres of the segments are in
coincidence. If this condition could always be realised, the
difference of the readings of the two scales would give directly
the distance measured in terms of the scale.
In practice it is of course necessary to find accurately the
difference of the readings when the optical centres are in coin-
cidence ; this difference is termed the " Index-error."
Two turns of the micrometer-screw correspond very nearly
with one division of the scale.
IX
An account of the investigation of the division-errors of the
scales is given in Dun Echt publications, Vol. II., pp. 11-51.
As the object throughout the following series of observations
was to determine not the absolute distance of the primary star
from its comparison stars but the change of these distances as
produced by proper motion and parallax, the same divisions
were employed throughout the whole of the observations of the
same distance, and no corrections for division- error have been
applied except for determining the Runs.
In reading the scales a pointer marks the centre of the field
of view of the microscope, and the division preceding and
following the pointer is read on each scale.
The segments and screen are reversed after each observation,
a second pointing is made, and the scales again read.
The instrument is then set for the position-angle and distance
of the second comparison star and directed by the circles to the
middle point for the new pair, a pointing made, the scales read,
the segments and screen reversed, the stars again pointed and
the scales read.
Thus the distance of each of the two opposite comparison stars
is measured once in each of the two opposite positions of the
segments, and so also the effect of Index-error is eliminated.
But such an observation is not complete, because it is non-
symmetrical — a progressive change in the relative temperatures
of different parts of the instrument may, as a matter of fact
frequently does, create a change of scale-value which can only
be eliminated by arranging the observations in symmetrical order.
Therefore the same observations are repeated in the reverse
order, that is to say, if the first pair be made in the order a b>
the second pair would be in the order b a. The instrument
having been reversed 180° in position-angle similar observations
are made in the order abba. To complete the symmetry of
the work, care was taken on the following night of observation
to arrange the order b a a b.
The following is a copy of the form in which the observations
were entered with the original record as entered by the
observer.*

The times entered are those of the Sidereal Chronometer
employed. In the block of " Readings the left-hand column
gives the reading of the scale division on the further side of the
pointer from the micrometer head, the webs approach the head
with increased readings of the head.
The middle column gives the division which is read on the
side of the pointer next the micrometer head, and the right-
hand column the micrometer reading on the named division.
The scale readings increase as the micrometer readings de-
crease ; therefore, if we refer the scale readings to the zero of the
micrometer, it is clear that were there no index-error, no error
of Run, and no error of the micrometer-screw, the true reading
for scale A. would be 105 divisions = 210 revolutions -f 1 * 600
revolutions. But if we suppose for the moment that the
division-errors are insensible, the error of Run on scale A. is
• 603 - • 600 = + 0 • 003 rev. over two revolutions, or + • 0015 per
revolution ; because if the pointings were exact, and there were
no division-error, both readings should agree or rather should
differ exactly 2 rev. But since there are accidental errors of
pointing in reading the micrometer scales, it is better to deduce
the Run from all the scale readings made in the same complete
observation, and this is accordingly done. In the example in
question we have the following differences in order : —

* The corrections for screw-error result from a very thorough investigation of the
screw made independently by Gill and Elkin, the two results being in close agree-
ment : —

where u is th« reading of the screw-head, and n the number of revolutions from 0*00.

Mean correction for Run - + 0 * 0030 per rev.
Having thus determined the correction for Run for one revo-
lution, the corresponding correction is to be applied to the
readings. These corrections might be applied only to the
reading of the division next the micrometer-head, but in this
way some accuracy would be lost. It is more exact to suppose
that our point of reference is the middle point between the
two divisions, and to shift our reference point in imagination,
one revolution farther from the micrometer-head. The
reduction is then precisely the same as if we used only one
division and a known Run, except that the mean of the readings
of the two scales is entered instead of the reading of only one.
Tables were prepared which give the correction for screw-
error applicable to the mean of the readings of the two scales
with the argument " lower reading."
The computation of the distances is then effected as follows :—
Where the sign of B-A refers only to the sign of the
correction for index-error.

The correction for chronometer error on July 6, derived from
comparison with the transit-clock, was +5 '8 m. which applied
to the mean of each pair of chronometer times of observation
gives the sidereal time for each pair of pointings as printed in
the results.
The refraction is computed, having regard to the readings of
the meteorological instruments, for each of these epochs ; and
being applied the result is the true observed distance free from
index-error. The mean of four such determinations of each
pair constitutes a complete observation for parallax. The reader
who may desire to verify the refraction corrections has only to
take the sum of the two distances marked r, the difference
between this sum and the column marked R is tlie refraction.
The figures in the column marked R give the distance in semi-
revolutions of the micrometer-screw. In computing the effect
of proper motion and aberration, and in the deduction of the
parallaxes, a semi-revolution (R) of the micrometer-screw has
been taken : —
R = 12"-865.
The mean results of these observations and all details of their
subsequent discussion are given in the Memoirs of the Royal
Astronomical Society, vol. xlviii., and need not, therefore, be
repeated here. The concluded results are : — .

On the publication of these results (loc. cit), I submitted to
the Lords Commissioners of the Admiralty a proposal to acquire
a new Heliometer, of seven inches aperture, for the observatory
to continue the work on stellar parallax thus begun, and to
determine the Solar Parallax by observations of Minor Planets.
Their Lordships responded favourably to this appeal. The
instrument was ordered from Messrs. Repsold and Sohne of
xvii
Hamburg ID 1884, was completed early in 1887, slightly modified
in a few details after inspection by me in Hamburg, and was
erected, and at work at the Cape before the end of ths same
year. This instrument has in every respect fulfilled the high
expectations which I had formed of its powers, and the results
already obtained, and which will shortly be published, will, I
trust, be found to have amply justified the liberality of the Lords
Commissioners of the Admiralty.
